Subject Re: Ideas to put a Spark ML model in production
Date Sat, 02 Jul 2016 07:45:03 GMT
Let's suppose you have trained a LogisticRegressionModel and saved it at
"/tmp/lr-model". You can copy the directory to production environment and
use it to make prediction on users new data. You can refer the following
code snippets:

val model = LogisiticRegressionModel.load("/tmp/lr-model")
val data = newDataset
val prediction = model.transform(data)

However, usually we save/load PipelineModel which include necessary feature
transformers and model training process rather than the single model, but
they are similar operations.

Thanks
